l Speciication of Letters Patent.

Patented Apr. 24, 191'?.

Application led November 19, 1913. Serial No. 801,764.

yTo all 'whom t may concern.'

Be it known that 1, JOSEPH P. LAVIGNE, a citizen of the United StatesofV America, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements in Valves,of which the following is a specification, reference being had thereinto the accompanying drawings. Y

ln the adjustment of valves and more particularly those adapted for usewith steam radiators in heating systems, it is desirable that provisionbe made whereby one valve can be regulated to control one, two or moreradiators and whereby after such regulation, the valve may be operatedto supply the maximum and minimum amount of steam for the radiator orset of radiators for which it has been regulated.

This invention relates to valves and more especially to a constructionthereof whereby a valve may be adjusted to have a capacity suflicientfor one radiator or any preferred number of radiators or the like andwhereby when once so adjusted it may be quickly manipulated. Theinvention also includes means for maintaining the parts in properoperative position and for compensating for slight irregularitiesincidental -to the construction of valves of this type. I

The invention consists in the matters here inafter set forth and pointedout in the ap pended claims.

In the drawings, l

Figure 1 is a view in longitudinal section of a valve that embodiesfeatures of the invention;

Fig. 2 is a view, in transverse section taken on or about line H--H ofFig. 1;

Fig. 3 is a view in detail and in section taken on or about line Ill-IIIof Fig. 1.

Fig. 4 is a view taken on line IV-IV of Fig. 3;

Fig. 5 is a-view in detail of the top of a sleeve closure, and

Fig. 6 is a perspective view of a plate forming part of my invention.

As herein indicated, a substantially cylindrical casing 1 has a lateralnipple 2, and is fitted at its open end portion 3 and the nipple forconnection with pipes or couplings. A substantially cylindrical sleeve 4hasa lower slightly enlarged portion 5, that is in screwthreadedengagement with the interior of the casing adjacent the nipple 2 so thatrotation ofA the sleeve brings a port 5 in the plate 21.

sleeve into more or less complete register with a lateral opening 6between the ports of the casing and nipple.

A tubular bonnet 7 preferably formed integrally with the casing 1, hasan interior flange 8 that forms oppositely disposed seats for an upperpacking ring 9 and a lower packing ring 10 respectively. A valve stemhas a cylindrical portion 11 rotatable in a guide aperture of thediaphragm 8 and a collar 12 that bears against the lower packing ring 10under the inuence of a spring 13. The latter is in-compression between awasher 14 in the bottom of a recess of a hollow handle spindle 15 and acheck nut 16 screwthreaded on to a reduced portion 17 of the stem 11.The stem itself is squared,

' splined or otherwise adapted for non-rotatable engagement with thespindle 15.

Connection between a squared orl attened -portion 18 of the stem 11 andthe closure 4 whereby the latter turns with the stem, is formed by aplate 19 non-rotatable and laterally movable on the stem that hasdepending ears 2O inbent or hooked under a the parts 20 and 21 on theportion 18 o f the stem. The plates and stem are so proportioned inrelation to a guide 'opening shown in Fig. 5, in the head of the sleeve4, that the plate 19 is free to move laterally a limited distance inrelation to the sleeve 4 while the plate 21 and spindle portion'18 aremovable in the plate 19 at right angles to the latters movement in thesleeve 4. To prevent the ears 20 from clenching the plates immovablytogether, the ears have shoulders indicated at 24 bearing against theupper face of the plate 21 and re'duced portions indicated at 25interlocking with marportion of the plate 27 while a latch 30 is Awasher 22 and pin 23 retain projected against the notched periphery of vthe plate by means of a spring 31. The latter is held by a cap 32screwthreaded over the handle 26. Avscrew 33 through the cap 32 acts asa stop to solimit the play of the latch 30 that it only allows movementof the turned against one of the shoulders of the indeX- plate peripherycorresponding to closed position. When the handle is moved to the othershoulder the v/alve is thus opened to supply a maximum amount of steamfor the radiators o`r set of radiators.

for which it is adjusted. The intermediate index points engaged by thelatch give proportionate supplies of steam.- If for any reason it isdesirable to change the adjustment of the valve, this may be done byunscrewing the screwV stop and permitting the latch to recedesufficiently to move completely around the index plate to admit theminimum amount of-steam.required to supply the radiators for which it isbeing set. Having determined the zero point in this manner the indexplate may be reset correspondingly and the stop adjusted to limit themovement of the handle as before.-

In addition to the quick manipulation and ease of-adjustment afforded bythe construction, the universal slide connections between the sleeve andthe 'stem permit the stem and sleeve to maintain independent alinementin the casing and bonnet without imposing strain upon either part sothat the mechanical difficulty of centering the sleeve which is inscrewthreaded engagement with the casing in exact aXial alinement withthe stem which is rotatable in the casing bonnet, is obviated.

Obviously, changes in the details of con- .struction may be made Withoutdeparting.

from the spirit of my invention and I do not care to limit myself to anyparticular form or arrangement of parts.

What I claim is 1. A valve comprising a casing having an inlet opening,a sleeve rotatable in the casing provided with a port adapted to bebrought into register with the opening, a stem journaled in thecasingextending through an opening in the head of the sleeve, a memberlaterally movablevon the stem in one direction, and laterally movable inthe head of the sleeve at right angles to the members movement on thestem and non-rotatably secured to the sleeve, and means for turning vthestem.

2. A valve comprising a casing having a lateral inlet opening, a sleevelongitudinally adjustable and rotatable in the casing provided with aport adapted to register with the opening and with a cross slot in itshead, a spindle `for turning the sleeve journaled in the casing, a platemember non-rotatably secured to the spindle and adapted to movelaterally in one direction thereon and in the cross slot of the sleeve,and a plate movable in synchronism with'said plate member and a headwith cross slotl in which the first plate is movable in one direction,and the plates coacting to couple the sleeve to turn with the stem. j

In testimony whereof I aiX my signature in presence of two witnesses.
